CHIMNEY-CAP.

SPECIFICATION forming part of Letters Patent No. 325,032, dated August25, 1885.

Application filed July 21, 1854.

T0 aZZ whom it may concern.-

Be it known that I, JEROME \V. lVn'rMoan, a citizen of the UnitedStates, residing at Erie, in the county of Erie and State ofPennsylvania, have invented a new and useful Improvement in the Cappingof Brick Chimneys, of which the following is a specification.

My invention relates to methods of protecting the mortar-joints of thebrick in the top course of the chimney from the action of the weather;and the objects of my invention are to accomplish this by having anadjustable protector over each joint, and to save the necessity ofhaving large caps specially constructed for each chimney or set ofchimneys. I attain these objects by the construction illustrated in theaccompanying drawings, in which Figure l is a perspective View of thetop of a chimney with the caps in place; Fig. 2, a longitudinal verticalsection through two contiguous bricks on the top of the chimney; Fig. 3,a vertical cross-section through the middle of the cap B, Fig. 1; Fig.4, a longitudinal. vertical section through the middle of cap B, Fig. 1;Fig. 5, an end View of the cap; Fig. 6, a side view of the same; Fig. 7,a side View of B, Fig. 1, resting in place on one end of a brick; Fig.8, a cross-section through one wall of the chimney, (showing one end ofa brick,) and a vertical longitudinal section through a cap similar tothat in Fig. 7, but

' having two flanges, the second one extending a short distance downover the joint in the inside of the chimney; Fig. 9, a modification ofthe improvement, showing the tongue of the cap separate from the cap,and passing through an oblong aperture in the middle of the cap B".

A is the chimney; 3, the cap; B, the cap with a flange, 2/, partiallycovering the outside of thejoint in Fig. l; B, the head of the cap withthe aperture; 13", the same without the aperture and with the flange; b,the tongue of the cap; 0 the space under the cap; 7), the

loose tongue of the cap; Zr, the head of this detached. fastening; a,the joint.

(No model.)

The caps are made of cast-iron, earthenware, or other suitable material.They are put in place while the mortar is soft in the joints. They areabout one and ahalf inch wide.

The space 2) enables the cap to set closer on the brick, and affordsroom for any mortar that may be pressed out of the joint when the cap ispressed to its seat. It is also of advantage to lessen the danger fromthe heav ing of ice under the cap.

The cap being kept in place by its weight and the projecting tongue, thedisintegration of the mortar in the upper tier of brick will beprevented and the chimney preserved in the exposed portion, where itsdestruction begins.

I am aware that there might be, instead of one, two tongues, one neareach end of the cap, or they might be placed on or through the flangeb,- but the forms represented in the figures are preferable.

I make available for protecting the chimney the main part of the uppersurface of the brick.

\Vhat I claim is 1. An oblong cap for covering thejoints of the brick ofthe upper course of a chimneytop, of a size to cover but a fraction ofeach of the ends of adjacent bricks, and having a broad tongueprojecting down between the adjacent ends of the bricks, substantiallyas described.

2. An oblong cap for covering the joints of the brick in the uppercourse of a chimneytop, of a size to cover only small portions of theends of adjacent bricks, constructed .with an end flange which projectsdown on the joint, and with abroad tongue projecting down from the underside into the mortar between the ends of two adjacent bricks,substantially as described, for the purpose specified.
